Abstract: Availability of genome sequences of pathogens has provided a tremendous amount of information that can be useful in drug target and vaccine target identification. The proteins/ peptides vaccines that could elicit the mucosal immune response are of great interest as potential vaccines. Recent new developments in the field of bioinformatics, genomics and proteomics have triggered the development of the insilico approach of vaccine design. This study follows the approach of ‘reverse vaccinology’ which employs the whole genome sequencing and advances in bioinformatics to identify vaccine candidates. The completely sequences genome of Helicobacter pylori 26695 (NC_000915) comprising of 1576 electronically annotated ORFs were analyzed in silico using a multi step computational screen to identify potential vaccine candidates. The selection parameters used were cellular localization, sequence similarity to known virulence factors and additional filtering criteria such as size. These screening criteria resulted in the selection of 316 ORFs with known and hypothetical proteins as potential vaccine candidates.
